ISO 12947-2:2016 PDF

Overview

ISO 12947-2:2016 - part of the Martindale series - specifies the procedure for determining the specimen breakdown (end-point) when measuring the abrasion resistance of textile fabrics using the Martindale method. The standard applies to most textile fabrics (including nonwovens) but excludes coated or laminated fabrics and fabrics specified to have a low abrasion wear life. Where apparatus requirements are needed, ISO 12947-1 is referenced; coated surfaces should be tested using parts of ISO 5470.

Key topics and technical requirements

• Scope and applicability: Applies to woven, knitted, pile and other textile fabrics and nonwovens; not for coated fabrics.
• End-point definition (specimen breakdown): Determined by inspection at fixed intervals based on thread breakage or worn-off area (partially or fully worn, with “fully worn off” defined as >75% exposed ground surface).
• Test motion and mounting: Circular specimens are rubbed against a standard abrasive medium in a translational Lissajous motion while the specimen holder also rotates; specimens
